摘要:
为研究梅雨对区域内河高水位的影响，利用南京市六合站1955—2021年梅雨期逐日降水量资料，分析梅雨特征量的基本统计特征及其相互关系，在此基础上对六合站年最高水位出现时间和梅雨期进行遭遇分析，并采用梅雨强度指数确定典型梅雨洪涝年。结果表明，梅雨各特征量之间存在显著相关性；梅雨各个特征值年际差异明显，近年来南京市出梅偏晚，梅雨期长度偏长；梅雨期丰枯周期起伏显著，梅雨量存在显著增加趋势；六合站发生年份大洪水时，基本与梅雨期重合，梅雨量显著偏多，梅雨期降水导致内河水位快速上涨并维持高位。
Abstract:
In order to study the influence of the plum rains for regional inland high water level, this paper uses the daily rainfall data of Liuhe Station from 1955 to 2021 to analyze the characteristic of the plum rains and their mutual relations. Then the occurrence time of annual maximum water level and plum rain period at Liuhe Station are analyzed and the plum rain intensity index is used to determine the typical plum rain flood years. The results show that there are significant correlations among the characteristic quantities of plum rain. In recent years, the emergence of plum rain is late and the length of plum rain period is longer in Nanjing. During the plum rain period, the period of abundance and drying fluctuate significantly, and the plum rain rainfall has a significant increasing trend. When the annual major flood occurred at Liuhe station, it basically coincided with the plum rain period, and the plum rain rainfall was significantly more, and the precipitation in plum rain period led to the rapid rise and maintained the high level of the inland river.
